โค๏ธOdd & Even (Montessori ๐Ÿ”ข Math 101 ๐ŸŽฅ Series ๐ŸŽ‡)

Today, we are revisiting Odd & Even Math Lesson (buy here). Only a month earlier, this concept was still confusing to Adrian even with all the visual help with counters. Today, however, at 39 months, he seems to be getting it!

Montessori math curriculum is generally introduced in the following order: (1) Number Rods (start with and introduce at around two years of age), then (2) Sandpaper Numbers, (3) Spindle Box, (4) Numbers Memory Game, followed by Odd and Even activity (also called Cards and Counters) which teaches a child what odd and even number is.

First, place numbers in random order on the rug since you want to make sure that your child knows numbers one through ten before introducing a concept of odd/even. Ask your child to set numbers one through ten horizontally at the top of the rug, and place counters under each, representing that number's quantity.
DSC_0066You can use traditional Montessori Numerals and Counters (like here) or you can make it yourself: you would need numbers 1-10, and 55 round counters (you can use marbles, wooden dots etc). We are using โค๏ธ๏ธ heart-counters, in addition to wooden ones.

To make this lesson even more illustrative, I set counters in pairs as friends ๐Ÿ‘ซ e.g. brother-sister (Adrian - Julia), Mommy-Pappy๐Ÿ’‘ (buy dolls here), or animal pairs (buy a deer family set here).

Such presentation made it obvious for Adrian to see when a number has a counter without a pair/on its own: meaning that the number is odd. As opposed to, when all counter-hearts have a complete set of pairs (two friends are holding hands๐Ÿ‘ซ "ta-ta-ta") that number is even.

 In this video, Adrian is summarizing which numbers are odd and which ones are even.
